INCUBATOR. 4 e

To all whom it may conccm: i

Be it known that I, A'noxzo Gnnann, a' citizen of the United States, residing at Austin, in the County of Travis and State of Texas, have invented certain new and useful Iuprovenents in Incubators, ot' which the following is a specific-allen.

M invention relates to iproveunmlsin incu ators, and the objectsmt' y-iiventim are: first-to provide eheaper and sai'er means in incubators which will autonatically turn in bulk each and every egg equally and continuously, or at intervals, as often during day and night as'required to prevent the yolks of the eggs from adherng to their' shells, without shaking or breaking the same during their incubation, and insure very part of each egg receh-'ing equal b'cefit of the temperature, moisture and cooling, without; opening the incubator door, especially during the last several days of their incubaton, thereby avoiding all danger from chillingthe eggs; second -to dispense with the extra labor required daily for opening the incubator door to turn the eggs by hand and often enough, and when done are seldon equally* turned; thirdto provide Safer means to enable the chicks to transfer thenselves to the brooder without injury or assistance and at the sane time pernit the unhatched eggs to be turned without opening the incubator door at a time when danger of ehilling the eggs' is greatest. I

r attain these objects by the inechanism illustrated in the accoupanyiug drawngs of which-^ i Figure l is a horizontal section of the incubator; Fig. 2 is a vertical cross section; Fig. 3 is a per pective of one of the cages; Fig 4- is a perspective View of one of the lot-king rods for the cages; Fig. 5 and Fig. G are details in section of a. cage.

'l`he ieubator easin'g is provided at one end thereof with a' power shat't (i journaled therein havi'g one of its ends passed through to the outer side of the incubatoi" wall for securiug to it the gear wheel 8. The worm screw 27 supported in a suitable n'anner on the outer wall of the ineubator nesbes with said gear wheel S and drives the same when any suitable power is applied to said woru screw 97 for revolving the same.

A plurality of portable revolving egg cages 3 are located in the -asing, each being specfi caton of Letters Pate t. v Application filed March 26, 1908.

provided wit h several expansible partitions 11, ha vingfin its lower edge a rivet hinge 1!) tor opening or elosing same all at Same: time by one and the same operation to open or closeeach cage 3 for filling it .with a single; line or row ot' eggs. The middle partitien ll'of 'ea'eh'of said eages bears upon the power belt 5 at'ter said'cages are tilled gwitlr eggs, the" opposite entls--of said cages being journaled in the hole or journal boxes 2 in the opposite walls of tleincibato easing.

The power belt 5 is'driven by pulley 24 o the i'uerend of said 'power shaft (3 said power belt being carried by several -loose plleys ltl supported in the easing by brackets', ;andsaid belt passesf under and 'in contact with the cages for revolving the same when suitable power is properly applied to'said worm screw 27 as aforesad. j

One end ot' each cage 3 is jourualed in a strip 23 Secured to the rear inside wall of the casing, and the opposite end of said cage is journaled in halt journal boxes 20 and 21 between two bars 18 and' 7 hinged together and Secured to opposite inside walls of the incubator near the jaml of its door as shown in Fg. 2, at proper height to ernit said cages to bear on said belt 5 as a oresaid, for revolving said egg cages. Fig. 3 shows one of the said cages 3 showing one of its journals 4 on its ends, also its three partitions lt provided in their lower edge, each with a rivet hin'ge 10 to permit said cage 3 to open and close. The cage is unlocked by withdrawing the split key 12 'from the key-bole 13 in the end of a 'od 14 whichextends through 'and may be witldra'wn 'froni the holes 15 in the upper edges of said three partitions 11 when said cage 3 nay be opened, and closed by reversing the operation.

The top half journal box bar 18 is free at its ends and is provided with hinges- 17 by whi'ch it is hinged to the top edge of said bottom bar 7 in such a uauner so that when said journals 4 are in said bottom halt jour- `nal boxes and the bar 18 is swung down saitlba''s 17 and 7 meet each other and form `said complete journal boxes 2, and when the incubatordoor is closed will keep said top journal `bar over said jouruals 4 to prevent them from slipping out' of their boxes until the incubator door is opened, when said top bar 18 may be swug up to allow the operator to remove one or all of said cages 3 when required for filling theni with eggs and when the chicks are hatched the power bars of said cages into said brooder hamnocl 22 as above described. Said hammock "consists of a web Secured at its edges'to the.

sides of the incubator box and located under the egg trays. 4 s

The frame and chambcr ofthe incubator and its heating, ventilating, or cooling and noisture compartments may be uonstructed in the usual or any suitable mamer with a suitable regulator for controllin heat to the jroper temperature in the incu ator chamer and having its incubating chambers so constructed to pernit same being provided therein with the mchanism as illustrated in the several laforesaddrawmgs. The incu 1. An incubator having a revolving device I for holding eggs in a single row, a partition across said devce having an external curvd v surface, and a belt movng n contact with sad surface, for -evolvng the devce.

2. A rotatable 'g-holdefor incubato's, a

comprising. anlelogated cage 'frmed with end plates and rods therebetween, and an intermediate parttion having .exterior surfaces constructed to bear upon a belt or the' like, for rotating the lolder.
